Working toward Digital JT65 WAS award…

May 30, 2012 | Amateur Radio | By: Mark VandeWettering

I’m currently working toward something something which I don’t normally do: an achievement award. For about two months, I’ve been trying to log contacts via the JT65 mode on ham radio, with the eventual goal of making contacts in every state. It’s not a particularly difficult award: I suspect that it will mostly require patience […]

The Beaglebone: an $89 Time Machine…

May 28, 2012 | Computer Science, Emulation, My Projects | By: Mark VandeWettering

At the Maker Faire, I splurged for a little bit of computing hardware called the Beaglebone. It’s an $89 ARM based computer that runs at 700Mhz, and includes a MicroSD card slot and Ethernet, as well as a USB connector. I wasn’t sure what I was going to use it for, but I frankly can’t […]

Photos from the eclipse…

May 21, 2012 | Amateur Science, Astronomy | By: Mark VandeWettering

Okay, these are the best of the photos that I snapped during yesterdays annular solar eclipse (well, it was really only a partial eclipse here). We had just left the Maker Faire, and were in the parking lot of Oracle on 10 Twin Dolphin Drive in Redwood City, CA. I took out my 4″ Meade […]

A Maker Faire Post Mortem…

May 21, 2012 | Rants and Raves | By: Mark VandeWettering

Phew. My legs are sore, and my voice is just returning to normal after a whirlwind two days at the Maker Faire in San Mateo. Thanks to everyone I bumped into and chatted with: I had a very nice time, and the partial solar eclipse was an added bonus (some pictures to come in a […]

States heard in the last week on JT65

May 12, 2012 | Amateur Radio | By: Mark VandeWettering

I’ve got something like 30 states worked via JT65 over the last month or so, but I’ve obviously heard a lot more than that. I took my listening log, extracted all the U.S. callsigns, and then wrote a simple Python/sqlite script to look up each state for the callsign, and see how many states I’ve […]

Countries heard (not worked) on JT65 in the last 7 days…

May 11, 2012 | Amateur Radio | By: Mark VandeWettering

Alaska, Argentina, Asiatic Russia, Australia, Austria, Belgium, Brazil, Canada, Chile, China, Cuba, Curacao, Czech Republic, England, Estonia, European Russia, Fed. Rep. of Germany, Finland, France, Gabon, Guantanamo Bay, Hawaii, Indonesia, Japan, Netherlands, New Zealand, Poland, Puerto […]

Beating the dead horse: the search for “quality” in radio amateurs…

May 11, 2012 | Amateur Radio | By: Mark VandeWettering

Last night the mailbox contained the latest copy of QST magazine, which always means at least a few minutes of interesting reading. I usually read the magazine more or less front to back, flipping through. I mostly enjoy technical content, but reading about other aspects of the hobby (contesting, etc…) as an interesting diversion. Sadly, […]

NJQRP’s “Chat With The Designers”

May 9, 2012 | Amateur Radio | By: Mark VandeWettering

I’ve often thought that the various ham radio podcasts that I like don’t really cater to the technical side of the hobby. Sure, you can get news from the Amateur Radio Newsline, and some nice introductory material on Ham Nation or the ICQ Podcast, but on the whole these podcasts don’t address technical issues very […]

One month of experience with JT65

May 5, 2012 | Amateur Radio | By: Mark VandeWettering

On the last day of March, I started using the JT65-HF program to do some digital operation on the HF bands. In the roughly month since then, I’ve logged contacts with 30 states, and 13 DXCC entities, using my ICOM IC-735 and a crappy 40m dipole that’s mounted far too low. In the last week […]
